AUTOVEICOLO E PROCEDIMENTO PER IL SUO FUNZIONAMENTO IN PARTICOLARE PER IL FUNZIONAMENTO DEL DISPOSITIVO DI AZIONAMENTO DELL'AUTOVEICOLO

摘要

An automatic clutch control device comprises an electric motor 10 connected via an output shaft 12 and a gearbox 14 having a crank 20 to a piston rod 24 of a master cylinder 30. Slave cylinder 60 is connected by a hose 50 to the master cylinder 30 so that when piston 38 is moved by the motor 10 a piston 62 in the slave cylinder 60 is displaced and operates a clutch. In order to detect a position of the piston 38 a sensor 70 is provided on the piston rod 24 and is connected to a control device 72. Chamber B of the cylinder 30, the hose 50 and a pressure chamber of slave cylinder 60 form a system section which is provided with a snifting bore 80 connected to a compensating container 86. In order to keep the volume constant, eg if the temperature increases, a snifting cycle is initiated which connects/disconnects the snifting bore 80 to the system section.
